Question

Read the following chemical equation. Mg(s) + H+ Cl− → Mg2+ Cl− + H2 What most likely happens during this reaction?

Magnesium gains two electrons.
Magnesium loses two electrons.
Chlorine gains one electron.
Chlorine loses one electron.

Answer 1

B

Explanation: just took the test, gl

Answer 2

Magnesium loses two electrons.

Step-by-step explanation:

• As clear from the reaction Mg converted from Mg(s) to Mg²⁺, so Mg converted from the oxidation state (0) to (2+).

∴ Mg losses two electrons.

• Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.

So, the correct choice is Magnesium loses two electrons.
